An anisotropic rotating cosmic string with Lorentz violation: thermodynamics and Landau levels
A. A. Araújo Filho, J. A. A. S. Reis, L. Lisboa-Santos
In this work, we generalize the spacetime induced by a rotating cosmic string, taking into account anisotropic effects due the breaking of the Lorentz violation. In particular, we…
